Abstract
A process for insulating electrical components located in a conduit from fire comprising mixing and pouring into the conduit a composition comrising a vinyl-containing polysiloxane polymer, an extending filler which is preferably alpha quartz, a platinum catalyst and a hydrogen-containing polysiloxane. The composition is allowed to surround the electrical components in the conduit and cured at room temperature to a solid silicone elastomer. Such a process has been found imminently suitable for insulating electrical components in a nuclear plant from fire for an extended period of time so as to maintain the electrical integrity of the components.
